CHARGING RAILWAY SYSTEM.

Application filed February 17, 191 1.

To all whom it may concern:

Be it known that I, GEORGE E. TITCOMB, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements in Charging Railway Systems, of which the following is aspecilication.

In plants of the type to which my invention relates there is a centralbin on each side of which is a series of coke ovens and there is a gasoutlet at the center of each oven, communicating with a main so that thecoal must be discharged into the ovens on each side of the gas outlet.This necessi- I tates, in large ovens, the use of two independent trackson which the lorries or cars travel so as to convey the coal from thelorry bins to the different coke ovens.

The object of the present invention is to provide means for driving acar on each track from one car so that only one motorman is required tohandle both cars.

In the accompanying drawings ;Figure 1, is an end view showing the cokeovens and the lorries or transfer cars located above the ovens; Fig. 2,is a view showing the lorries or transfer cars located under the lorrybin; Fig. 3, is a plan view of one of the transfer cars; Fig. 4, is anend View of the car shown in Fig. 3; Fig. 5, is a diagram plan View ofthe plant, and Fig. 6, is a diagram illustrating the electric wiring bywhich the two cars are controlled by a motorman on one of the cars.

Referring in the first instance to the diagram Fig. 5, A is the lorrybin of sufficient size to store a quantity of coal. B-B are the cokeovens mounted on each side of the lorry bin and over the series of ovensare located the tracks CC on which the cars D travel in conveying thecoal from the lorry bin to one of the series of ovens. EX- tendingthrough the roof of each bin at a point midway between the sides of theovens is a gas pipe B which communicates with the gas main B and at eachside of the coke ovens are doors 6-6, which are closed during the cokingprocess and opened when the coke is to be discharged. These doors can beoperated by independent mechanism, if desired, but I prefer to operatethem from the mechanism on the cars as described hereafter. The locationof the several gas pipes at the center of the coke ovens necessitatesthe use of two tracks CC', one track Specification of Letters Patent.

being located above the ovens on one side of the series of gas pipes andthe other track being located on the opposite side, as clearly shown inthe drawings. Consequently, two cars D-D are necessary for the propercharging of the coke ovens with coal and as the charging should be doneat the same time both cars must be loaded and driven simultaneously. Ifthe cars were electrically driven in the ordinary manner, this wouldnecessitate two sets of electric mechanism on each car and two motorinenor drivers, but by my invention I am enabled to dispense with theservice of one motorman and to drive both cars from a point on one car,not only reducing the cost of operation, but making easily possible thesimultaneous movement of the cars and the simultaneous discharge of thecoal into the ovens. The lorry bin A is provided with six dischargespouts a in the present instance the discharge of coal being controlledby valves or gatesa" operated in any suitable manner and the lorry carsare each provided with three spouts 0! having valves or gates d (Fig.4:). These valves d arein the form of sliding plates which are connectedto arms on a rock shaft 0Z mounted on each car, on the rock shaft is ahand lever (i by which it is turned. The valves may be operatedsimultaneously in any other suitable manner so as to quickly dischargethe coke into the oven. The oven has a series of openings 6 throughwhich the coal is discharged from the cars. These openings are of tracksC. Trolley poles (not shown) are mounted on the cars DD' for conveyingcurrent to and from the two controllers II and between the controller Iand the motor m'-N The controller I governs the motor N on the car D,while the controller I governs a similar motor on the car D. 70 is theresistance for each controller and N is the field for the motor on thecar D and N is the field for .the motor on the car D". i

, mm are the armatures and s-s.' are the causes current to be deliveredfrom the feed mains iz' to the connecting wires 71, i 11 i and thence tothe motor mN Obviously both controllers include means for reversingtheir respective motors.

The arrangement of the mechanism may be varied according to the type ofcar used. In the present instance, referring to Figs. 3 and 4, ee arethe Wheels mounted on the axles EE of the cars D. The axle E is thedriven axle, driven from the shaft F through the medium of gears f and 6N is the motor. motor is geared to the shaft F through gearings' ff Inorder to operate the doors b b, of the oven over which the cars DD arelocated, I provide a motor G on each car and this motor is geared by aworm g and worm wheel 9 to a driven shaft G on which is a drum 9 a ropeor chain H extends from the drum and around a sheave h on a framecarried by the car, and the rope has a hook it at its free end to engagean eye on the door I) (Fig. 1) so that When the hooks are coupled to thedoors and the motors started through the controller I both doors of theovens will be raised so that a pusher can enter the oven to push out thefinished coke, or a device ma be inserted to levei the coke in the ovenbe ore coking. In

some instances the door operating mechanism of the two-cars may beindeperrdeneof one another. Then there will be a controller I on eachcar.

In operation it will be seen that the lorry bins are charged with coalby any suitable bin the valves or gates 65' in the bottom of Thearmature shaft M of this 1 to level the charge, if necessary. After theanother oven.

mechanism and the lorry cars are loaded simultaneously from the bin.Then, as soon as the'cars are charged and the doors are closed, theoperator, through the medium of the twocontrollers II, traverses thecars over the tracks simultaneously and when the cars are over theopenings of a particular the cars are opened and the coal flows frofgthe cars through the openings directly into the oven; the coke chargehaving been pr viously removed. Preferably, while the cai are'locatedover theoven and beforethey are discharged, the hooks h of the hoistingchains II engage the eyes on the doors I) of the oven and the mechanismcontrolling the drum shafts is operated, causing the chain to Wraparound the drum g and lift the doors. While the doors are in the raised'position a discharging apparatus enters the. oven at one side and pushesthe coke out of the oven at the opposite side. When this dischargingapparatus is removed the doors are lowered and the gates of the cars arel opened, allowing the coal to flow directly into the oven and whenthe'oharge has been completed suitable mechanism can be used coal isdischarged from the cars the mechanism is operated so as to traverse thecars back to a position under the lorry bins, where a fresh supply ofcoal is obtained for I claim The combination of two tracks; a cararranged to travel on each track; electric mechanism for driving thecars; and twof,
